How do I protect my original design when working with a factory?

Talk · B2B / custom / OEM
A designer has sketched an original ring and is about to send it to a factory for samples. They worry the factory may copy or reuse the design, and want practical steps to protect it that do not depend on a lawyer for every detail.
Protect the design in layers: keep records of who created it and when, sign a confidentiality agreement before sharing details, consider registering the design in the countries that matter before it is made public, and put ownership of tooling and moulds into the contract. None of these is a guarantee, and the rules vary by country, so take legal advice for anything valuable.
1. Keep records
Our advice Date your sketches and files, keep the original files and emails, and note who contributed what. In a dispute, a clear record of authorship is the first thing anyone asks for.
2. Use a written confidentiality agreement
Our advice Before sharing the full design, sign an agreement that says the factory will keep the design confidential and use it only to make your order. Ask that it covers employees and subcontractors.
3. Think about registration before disclosure
Fact WIPO explains that jewelry designs can be protected as industrial designs, that protection is territorial, so you register in each country or region where you need it, and that an international application can cover several territories. It advises filing before the design is made public, because disclosure can affect novelty, although some countries allow a grace period.
Uncertain Whether you need registration, and where, depends on your markets, your budget and the value of the design. We cannot say whether a particular design qualifies, and copyright or other rights may also apply in some places.
4. Control what the factory has
- Share only what is needed for each stage.
- Mark drawings and files with your name and date.
- State in writing that the design, patterns, models and moulds made for your order belong to you.
- Ask what happens to the tooling, wax models and files after the order, and agree that they will not be reused or sold.
5. Contract terms to include
- A ban on selling the design or similar items to others.
- A clause on ownership of tooling and samples.
- A right to inspect or collect the tooling.
- A confidentiality period that continues after the order.
- The governing law and how disputes will be resolved.
6. Practical habits
Our advice Order from a factory you can visit or check, avoid sharing your whole line at once, and keep a signed sample as evidence. If you see your design elsewhere, keep dated proof and speak to a lawyer in the country concerned.
It depends A strong contract matters less than a good relationship with a factory that values repeat business. Both are useful, but neither replaces registration if the design is valuable.

Other perspectives from the ZKZ team
Register before you publish photos or show the design at fairs. Public disclosure is the step that can reduce your options in many countries.
Ask the factory about its own policy on designs and moulds. A professional supplier should have a clear answer and be willing to put it in writing.
Wax models, moulds and casting trees are physical copies of your design. Agree who keeps them and what happens to them after the run.
